Overview
Overview
Left anterior fascicular block, which is more common than left posterior fascicular block, may be due to damages to the left anterior fascicle as it passes through the left ventricular outflow tract, such causes include aortic stenosis, hypertensive heart disease and cardiomyopathy. It can also be caused by congenital heart diseases such as Atrial septal defect, atrioventricular septal defect, single ventricle, e.t.c However, life threatening conditions such as myocardial infarction must be promptly identified and treated accordingly.
